The Curcubit beetle (Diabrotica speciosa) is a pest of maize, the cucumber family, squash, tomatoes, and several other hosts. Surveys were conducted because of the presence of potential host material in Wyoming and the high potential for establishment after introduction. Although Diabrotica speciosa is currently only found in South and Central America, several species of curcubit beetles are endemic to the United States.
The Curcubit beetle portion of the Small Grains Commodity Survey is conducted by the Wyoming Pest Detection / CAPS Program. The survey is visual examination of the host plant. Host plant fields were swept with a net and visually surveyed June through August. Sweep net samples were examined for suspects at the University of Wyoming.
One hundred eighty fields have been swept with nets and visually examined in nine Wyoming counties. The Curcubit beetle has not been found in Wyoming.
